Know exactly where your dog is, even when he or she is out of sight. Everything a hunter could possibly need to locate his dog is accessible from one compact and well-designed handheld unit. The TEK's compact transceiver features a backlit LCD display and integral electronic compass. Used as a GPS, the scalable screen provides a 75-mile diameter view and multiple-waypoint capabilities. Paired with the tracking collar-receiver, it shows a dog's location from up to 7 miles away and reports the dog's status (stopped or direction of movement). Designed with SportDOG's DRYTEK technology, the transceiver is waterproof and submersible to 25'. It can be programmed to track up to 12 dogs at once. Each system includes one collar receiver with an AC wall adapter for recharging. Provides a minimum of 20 hrs. use between charges. Works with the Add-A-Dog Training/Tracking Collar (443570).
